My man you got like 3 people trying to explain it to you. Light is light. If you want your low watt cobs to act like a HID, then cram them together in a single fixture and hang it high in the center. (Look at spectrum king for a commercial example like this)
Personally I'm gonna unsub and move on, I'm out of troll food.
no your not interpreting it correctly.I guess the online light square inverse law calculator is wrong.
solar city just got a big bail out, they have been failing. Love the long term vision, but currently they are no more than a financing play.Bullheaded? Are you saying I'm bullheaded? Haha. Word up man. I'm gonna go bite my fingers and watch my solar city shares.
sure. smaller than a filament in factso unless you can place 1000 watts of cobs in the size of the filament
whats an elevator pitch ? sorry haven't had my morning wake an bake yet
An elevator pitch is something that can be summed up during a brief elevator ride. A sales pitch if you will. It's a term used in the business world. Something concise and to the point.whats an elevator pitch ? sorry haven't had my morning wake an bake yet
dude THINK where did the other 500 ppf go ? and please stop confusing PPFD with PPF.Ok let me remove light types from this.
ANY LIGHT that produces 1000 PPFD AT 6 inches from source will only be producing 500 PPFD at 8.1 inches from source. So it's providing 2.1 inches of 1000-500 PPFD on and in to the canopy.
So what you are saying HID is still going to outperform cobs even boxed around trees? Under-driven cob diminishes so quickly it won't penetrate the length of the branches by what is being stated here.I fixed one of my data bases that messed things up.
Yes I don't think you're saying anything that I'm not implying. As for side lighting and what not if you boxed cobs around a 6 foot plant it would crush hid. That's just single plant modified sea of green.....just the sea is shaped like the inside of a trash can.
These basis are off PPFD. So I have no clue of the green yellow penetration you speak of .....if it's not included in what a PPFD meter would calculate then it can't pe concluded in the base of my data. Sounds a little snake oil to me as PPF will measure yellow and green to what ever its mathematical value is for radiation.......no?
Light isn't lost. This is all you are missing.Ok let me remove light types from this.
ANY LIGHT that produces 1000 PPFD AT 6 inches from source will only be producing 500 PPFD at 8.1 inches from source. So it's providing 2.1 inches of 1000-500 PPFD on and in to the canopy.
ANY LIGHT that produces 1000 PPFD AT 24 inches from source will only be producing 500 PPFD at 34 inches from source. So it's providing 10 inches of 1000-500 PPFD on and in to the canopy.
Are there any objections? I'm talking here about single light source no side lighting no wazoo tricks.
If there's objections then I'm sorry but contact the invers square law calculations invented by a dead scientist. These are facts!

I lied, the other thing you are missing is that PPFD is a spot reading.Fig 1
Actual meter readings at 12 and 18"

It doesn't calculate reflection that's likely happening. But they're close enough.
So the calculator is wrong and so are the actual PPFD meter readings according to you?
